Add option to control "GPU Performance Counter"

[cmd-ntrf]

Commands required to enable NVIDIA gpu performance counter for all user

echo "options nvidia NVreg_RestrictProfilingToAdminUsers=0" > /etc/modprobe.d/nvidia.conf
systemctl stop nvidia-dcgm
nvidia-smi --lock-gpu-clocks=tdp,tdp

systemctl stop nvidia-dcgm may not be required if the other two are done. Testing further currently.

Confirming that systemctl stop nvidia-dcgm is not required at least with the recent version of ncu-ui

It may still be a good idea to allow to disable it for older versions of the profilers.

PR to fix this is open.

Note that nvidia-smi --lock-gpu-clocks=tdp,tdp is not strictly needed, there is an option --clock-control=none to ncu, which prevents it from trying to set the clock. Setting the clock is an issue only in the context of MIG, so it is is a separate problem.
